Abstract
Proposed are an anode active material, a method for preparing the same, an electrode including the anode active material, and a secondary battery including the same, in which when a charge curve of a charge-discharge cycle measured by incremental capacity analysis (ICA) performed on a half-cell is converted into a differential capacity versus voltage curve (dQ/dV) by normalizing the charge curve with respect to the total charge capacity of each cell, the maximum peak height (Peak A) observed in a voltage region of 0.4 to 0.5 V is equal to or greater than 3.5 V<sup>-1</sup>.
